Mobile Application Prototype for Foot Self-care Support for Persons With Diabetes: A Human-Centered Design Approach

The human-centered design approach has gained prominence in the development of mobile health solutions. However, its application to support foot self-care for persons with diabetes has not been extensively explored. This study aims to develop a mobile application prototype using a human-centered design approach to support foot self-care for persons with type 2 diabetes. The project used mixed methods, including a scoping review, patient interviews, a Delphi panel, and an acceptability and usability study of an educational booklet. This three-phase approach encompassed defining the context of use, specifying user requirements, and developing design solutions. This article specifically details the third phase of the project: the development of the low-fidelity prototype. Functionalities such as daily reminders for foot care, notifications for medical appointments, communication features with healthcare professionals and peers, and repositories of videos and educational content were integrated into the design. These features were tailored to address user needs, emphasizing knowledge enhancement in self-care practices. The human-centered design approach enabled the creation of a comprehensive prototype with essential functionalities and robust educational content, filling gaps in the digital health market and empowering persons to better manage their foot health.
